Incidentally detected anomalous origin of left circumflex artery from right pulmonary artery in an adult with aortic stenosis and coarctation

A previously asymptomatic fifty year old male presented with shortness of breath and chest pain for past 6 months. He underwent a transthoracic echocardiography which showed presence of a bicuspid aortic valve with severe stenosis. He further underwent CT angiography for evaluation of coronary arteries and aortic root dimensions. Review of CTA images incidentally revealed an anomalous origin of left circumflex artery (LCx) from the right pulmonary artery (RPA) (Figure 1A-B). The left anterior descending artery (LAD) and the right coronary artery (RCA) were dilated and extremely tortuous with extensive collateralization to LCx over the anterolateral epicardial surface of left ventricle (LV) (Figure 2A-B).
